Abstract: A system and method for feeding comminuted cellulosic fibrous material such as wood chips to the top of a treatment vessel such as a continuous digester provide enhanced simplicity, operability, and maintainability by eliminating the high pressure transfer device conventionally used in the prior art. Instead of a high pressure transfer device the steamed and slurried chips are pressurized using one or more slurry pumps located at least thirty feet below the top of the treatment vessel and for pressurizing the slurry to a pressure of at least about 10 bar gauge. A return line from the top of the digester may, but need not necessarily, be operatively connected to the one or more pumps and if connected to the pumps the pressure in the return line may be reduced utilizing a pressure reduction valve and/or a flash tank. Steam from the flash tank may be used in steaming the chips. Pressure relief prevention may be provided by isolation valves in the lines leading to and from the top of the treatment vessel controlled by a controller which is responsive to the pressure sensed in the slurry line leading to the top of the treatment vessel.

Abstract: A marine jet drive apparatus includes a power trim unit coupled to a jet deflector for remote trim positioning of the jet and for controlling steering deflection of the jet to either side. An auxiliary rudder also coupled to the jet deflector to vary the effectiveness of the auxiliary rudder with the trim positioning. The main jet deflector is a tubular extension of the jet nozzle and is mounted for trim positioning. The main jet deflector is a tubular extension of the jet nozzle and is mounted for trim rotation about a transverse axis by a gimbal ring. A powered trim control link is connected to the ring for setting of the jet with respect to the horizontal. The jet deflector is pivotally mounted within the gimbal ring to create a vertical steering axis for angular positioning of the jet deflector through the normal 40 DEG  to 50 DEG  for conventional type steering. The rudder has an upper portion projecting between a pair of depending walls of the jet deflector and with the opposite sides slidably engaging the opposing portions of the walls. As the trim position of the jet deflector changes, the sliding coupling automatically moves with respect to the pivot axis of the auxiliary rudder and varies the effective center of rotation of the coupling with respect to the axis of the deflector and the rudder axis.

Abstract: An internal combustion engine comprising a spring-loaded engine valve (13) actuatable by means of a cam (2), a tappet (4) and a push rod (10), the cam (2) having a pre-lift ramp (5) for effecting exhaust braking of the engine. A single piston (6) is slidable in the tappet (4) between a bottom stop (8) and a top stop (7) therein and biased by a spring (9) against the top stop (7) and/or the push rod (10). The tappet (4) has an inlet (14) for hydraulic, control fluid to bias the piston (6) towards the top stop (7). There is also a valve (17) preventing escape of hydraulic fluid from the tappet (4) during exhaust braking. During normal operation of the engine when the pre-lift ramp (5) lifts the tappet (4) the valve (17) is held open and hydraulic control fluid flows from the tappet (4) so that the piston (6) contacts the bottom stop (8) and the engine valve (13) remains closed, whereas during exhaust braking of the engine when the pre-lift ramp (5) lifts the tappet (4) the valve (17) is closed and hydraulic control fluid cannot flow from the tappet (4) so that the pistons (6) remains against the stop (7) and the engine valve (13) opened to effect exhaust braking. <IMAGE>

Abstract: An ultra high pressure water jet cutting nozzle is disclosed which comprises a lightweight poppet valve assembly coupled by a lost motion connection to a valve actuator. The poppet valve assembly seals directly to the jet-forming element of the nozzle insuring continuous high pressure fluid in the system at all times.
